STEM WINDING AND SETTING WATGH.

A tlication filed December 80, 1908.

Specification of Letters Patent.

To all whom it may conccm:

Be it known that l, HENRY if. ZllATA- LENE, a citizen of the United States, and a resident of Boston, in the county of Sulfollc and State of Massachusetts, have invented certain new and useful improvements in Stem llinding and Setting ll atchcs, of which the following is a specification.

This invention relates to watches in which 30th the winding and setting operations are performed through the agency of the winding stem, and resides in certain features of construction and arrangement hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a front elevation, partly in section, of a watch embodying my invention; Fig. 2 is rear elevation of the upper portion of the watch with a part of the back broken away; and 3 is a vertical section on the line .r-a; in Fig. 2.

The watch illustrated in the drawings comprises a center 2, a bezel 3, a crystal i, a cap 5 and a hinged back 6, which parts may be of the usual or any suitable construction except in so far as the configuration of certain of these parts may need to be modified in order to receive and cooperate with the mechanism hereinafter described.

The case formed by the parts above described is adapted to receive a watch movement which may be of any desired construction, so long as it is provided with a winding .stem which may be rotated to wind the watch when in its normal position and may also be moved longitudinally into setting position and then rotated to set the watch. A portion of such a winding stem is shown at 7, and the upper end of said stem 7 is provided with a cylindrical terminal portion or winding terminal 8 which is located in a recess 9 in the center 2 of the watch case and forms, in effect, a pat of the winding stem. Said winding terminal 8 is provided with two circumferential grooves 10 and 11, each preferably bounded on its upper side by an inclined surface and on its lower side by a horizontal ledge, and a catch 12 having beveled upper face is arranged to move horizontally toward and away from the winding terminal 8 at one side of the latter, being normally pressed forward by means of a spring 13 to which it is attached and which is secured at one end to the center 2 of the watch case, as shown in Fig. 2.

A vertical notch 14 of sufficient width to {receive the catch 12 connects the annular E grooves 10 and 11, and the upper end of the l winding terminal 8 is provided with means whereby it and the winding stem may be rotated well as moved longitudinally inward andoutward as her inafter described. In the particular construction illustrated, provision is made for imparting these movements to the winding terminal by means of an eye secured thereto and a link 1.6 passing through said. eye, which eye and link serve as a means for suspending the watch from a neck chain or a chatelaine pin, this arrangement being particularly designed and adapted for use in locket watches as set forth in a prior ap plication for U. S. Letters Patent filed by me on the 25th day of June, 1908, Serial No. 440,217, in which a locket watch construction of this sort is described and claimed. This particular arrangement for suspending the watch is not an essential part of my present invention, however, and may be replaced by any other suitable means for imparting the desired movements to the winding ter minal and stem, whether the watch is suspended from said terminal or not. As thus constructed, when the winding terminal 8 and stem 7 are in their normal or winding position, which is that shown in 3, the catch 12 overlies the horizontal ledge at the l bottom of the upper annular groove 10 and l thus prevents outward movement of the winding terminal and stem unless the same are rotated into such position as to bring the vertical notch 14- directly beneath the catch, but after this has been done the winding terminal and stem may be pulled outward until such movement is arrested by the engagement of the catch 12 with the horizontal ledge at the bottom of the lower groove 11, whereupon the parts will be in position to set the watch by rotating the terminal 8. After the watch has been set the winding stem may be pushed directly inward into winding position, by which movement the catch 12 will be pushed outward by the action of the inclined face above the lower groove 11, and as 1 soon as the upper horizontal ledge passes beneath the catch the latter w'll be thrown into the position shown in Fig. 3 by means of its spring 13, which may be convenien ly arranged to play in a space provided for the purpose between the inner edge of the back portion of the watch case.

In case the outer end of the winding ter- 6 and the outer edge of the cap 5 at the upper T minal 8 is provided with an eye 15 for suspending the watch, as shown, or with equivalent suspending means, the plane occupied by this eye should be so related to the location of the notch 14 that the normal position assumed by the watch when suspended will be one in which the catch 12 is out of register with said notch 14, so as to prevent an accidental or prema ure outward movement of the terminal 8 from being brought about by the weight of the watch, or a pull upon it.

vlhile my present improvements are applicable to stem winding and setting watches in general, they are particularly adapted and intended for use in locket watches which are suspended directly from the outer end of the winding stem, as set forth in my prior application above referred to, and have the advantage, as compared with the particular construction shown and described in said prior application, that the necessity for opening the watch case in order to set the watch is avoided.

I claim as my invention 1. A stern winding and setting watch comprising a winding stem having at its outer end a terminal portion mounted to rotate and to move longitudinally in the case of the watch, said parts being provided respectively with two annular grooves connected by a notch and witn a movable catch arranged to enter one or the other of said grooves, according to the longitudinal position of the winding stem, and adapted to pass through said notch from one groove to the other.

2. A stem winding and setting watch comprising a winding stem having at its outer end a terminal portion mounted to rotate and to move longitudinally in the case of the watch, said terminal portion being provided with two annular grooves located one above the other and having horizontal lower walls to form stop faces, a spring-actuated catch carried by the watch case and adapted to enter one or the other of said grooves, according to the longitudinal position of the winding stem, and having a stop surface on its under side to cooperate with the stop surfaces of the respective grooves, and means carried by the outer end of said terminal portion for suspending the watch.

A stem winding and setting watch comprising a winding stein having at its outer'end a terminal portion mounted to rotate and to move longitudinally in the case of the watch, said terminal portion being provided with two annular grooves located one above the other and connected by a vertical notch, and a springactuated catch arranged to enter one or the other of said grooves, according to the longitudinal position of the winding stem, and adapted to pass through said notch from one groove to the other.

e. A stein winding and setting watch comprising a winding stem having at its outer end. a terminal portion mounted to rotate and to move longitudinally in the case of the watch, said parts being provided respectively with two annular grooves located one above the other and connected by vertical notch and with a spring-actuated catch arranged to enter one or the other of said groov .s, according to the position of the winding stem, and adapted to pass through said notch from one groove to the other, and means for suspending the watch carried by the outer end of said terminal portion and so arranged that said catch and notch are normally out of register with each other when the watch is suspended.

In testimony whereof, I have hereunto subscribed my name this 28rd day of December, 1908.
